Keith Croxford

VOIP Expert and Social Engineer

Over the past 14 years I have been involved in information technology. 10 years of this has been focused on carrier / ISP voice and data networks.  I've built networks from the ground up. Literally.  I've worked on everything from outside plant (the wires in the ground) to the devices that deliver VOIP services to your home or business. 

A few things I've done with my career : 

Contracting with the US Army to build fiber optic infrastructure for their secure and non-secure networks. 

Deploying Metaswitch based voice services to businesses. 

Upgrading a network to be MPLS capable which allowed an ISP to add a lot of new services. 

Being part of an engineering team that lead Vonage to purchase Telesphere Networks

Creating fraud detection and analysis tools to stop VOIP hackers. 

Frequently I am asked to teach a concept to someone. This lead me to create my Udemy instructor profile. 

I strive to make these teaching sessions informative, fun, and upbeat.
